Calibrating the tube circuit
A tube calibration function is available in the device to enable use of different tube cir-
cuits and accessories. During tube calibration, the resistance of the circuit upstream of
the air outlet is determined, which forms the basis for correct pressure measurement.
Perform tube calibration when changes have been made to the system upstream of
the air outlet. These may include connecting and disconnecting of the following com-
ponents, for example:
•
Bacterial filter, humidifier, tube circuit, FiO
2
sensor etc.
Risk of injury due to incorrect pressure measurement!
If the device is operating with incorrect calibration data, the
pressure measurement may be distorted.
Ö
Before commissioning and changing the tube circuit, per-
form tube calibration.
To calibrate the tube circuit:
Please note:
During tube calibration, the patient tube circuit must be open and ven-
tilation switched off. A mask can be connected.
1. On the home screen, navigate to “System” and press the MFK.
2. Navigate to “Calibrate Tube” and press the MFK.
During calibration, the system shows
“Run...”.

3. If the calibration was successful, “Ok” will
appear after a few seconds.
To finish, press the MFK. The calibration data
are then applied. Until then, you can cancel
calibration at any time by pressing the Escape
key.
